EZAudio - an iOS/OSX audio processing and visualization framework

I just finished working on an audio framework for iOS and OSX called EZAudio. It's a universal API that provides cross-platform access to microphone input, reading and seeking through audio files, recording, generic playback, and various CPU and GPU-accelerated audio waveforms interface components.

It's been a labor of love brewing for a while that drew inspiration from the amazing audio engine and novacaine. I'd love feedback on it so I can continue to develop it and make it better!
